This problem may occur suddenly, and both laptops might be running Windows 11 without any issues. In this article, we'll discuss the potential causes and solutions to help you get your headphones working again.

Potential Causes

There could be several reasons why your Bose QuietComfort 2024 headphones are not being recognized by Windows 11:

• Outdated Bluetooth drivers
• Corrupted Bluetooth system files
• Interference from other Bluetooth devices
• Hardware issues with the headphones

Solutions

1. Update Bluetooth Drivers

Ensure that your Bluetooth drivers are up-to-date. You can check for updates by:

1. Pressing the Windows key + X and selecting Device Manager
2. Expanding the Bluetooth category
3. Right-clicking on your headphones and selecting Update driver
4. Choosing "Search automatically for updated driver software"

2. Repair Bluetooth System Files

You can try repairing the Bluetooth system files using the following steps:

1. Pressing the Windows key + X and selecting Command Prompt (Admin)
2. Typing "wmic BSFilter get All /format:list > bth.txt" and pressing Enter
3. Opening Notepad and selecting "File" > "Open" > navigating to the location of the saved bth.txt file > opening it
4. Locating the line that starts with "Name = "BTHPORT_xxx_xxx_" and copying the value after "xxx_xxx_"
5. Typing "powershell.exe -ExecutionPolicy Bypass -Command & 'Add-Type -TypeName @"namespace Root.Microsoft.Management.Infrastructure { [System.Runtime.CompilerServices.CompilerGenerated] [System.Runtime.InteropServices.ComImport] [System.Runtime.InteropServices.Guid("{56F88C52-FCE3-4EBD-8B40-10C3B73C868F}")] [System.Runtime.InteropServices.InterfaceType(1)] public interface IWmiObject { [System.Runtime.InteropServices.MethodInfo("InvokeMethod", Type.GetMethod("InvokeMethod", new Type[] { Type.GetType("System.String[]"), Type.GetType("System.Object[]") }))] public virtual object InvokeMethod(System.String[] parameters, object[] args); } } ; $ErrorActionPreference = "Stop"; $namespaceName = "Root.Microsoft.Management.Infrastructure"; $className = "MSFT_BT_Device"; $filter = "Name = 'BTHPORT_$($BTHPORT)'"; $searcher = New-Object -ComObject "WbemScripting.SWbemLocator"; $searcher.ConnectServer(); $searcher.Query($namespaceName + ":" + $className + "." + $filter); $device = $searcher.Get(); $device.InvokeMethod("Enable", @(0)); $device.InvokeMethod("EjectMedia", @()); $searcher.Quit();" and pressing Enter

Replace "$BTHPORT" with the value you copied in the previous step.

3. Disable Other Bluetooth Devices

Disable other Bluetooth devices that might be causing interference. You can do this by:

1. Pressing the Windows key + X and selecting Device Manager
2. Expanding the Bluetooth category
3. Right-clicking on the interfering device and selecting Disable
